" a sEraight edge 01 0Eher guiding edge; Eo provide an improvedarrangemen; which can be easily and economz'cally manufacEured anal ingeneral, iE is Ehe object 0f Ehe invenEiou Eo provide an v improvedpencil construction of Ehe Eype re- 1 ferred Eo.

Other objecEs and .advantages cf Ehe invention Will be understood byreference E0 Ehe following specification and which a pencil embodying aselected form of Ehe In Ehe drawing, Figs. 1 and 2 are edge and. sideviews respec-Eively of Ehe pencil;

Fig. 3 is a, c1ess section 0n Ehe 1ine 3-3 0f Fig. 4 is a cross sectionsimi1a1 Eo Fig. 3 but showing a modified arrangement; and

Fgs. 5, 6 and 7 illustrate various situations in Which Ehe improved.pencil construction may be advantageously used. Referring now Eo Ehedrawing Ehe pencil comsEruction shown in Figs. 1, 2 and 3 comprise anelongated body 10 which may conveniently be 0f wood 01 0Eher suitablematerial, Ehe body being cf relatively wide 01 Ehin rectangular crosssec- Eion, as clearly shown in Fig. 3.

In one of Ehe wide faces of Ehe body 10 Ehere is recessed a, sErip 11 oflead o1 0Eher suitable wriEing material. As shown in Fig 3, Ehe leadastrip 11 may be of substantially square cross sec- Eion, but it may Feeof rectangular or 0Eher crosssectional shape. 'Ihe lead is preferablyrecessed inEo one of Ehe wide faces so EhaE when Ehe penci1 is used, iEmay be placed with iEs wide leadcontaining face against Ehe straightedg6, in which case Ehe engagement of Ehe wide peneil face Will preventEurning of Ehe pencil and Ehereby facilitate Ehe accurace following of astraight edge or 0Eher guide member.

So .as Eo readily disEinguish Ehe lead-containing side of Ehe pencilfrom Ehe opposite side, Ehe corners of Ehe opposite side are preferablybeveled 01 0Eherwise Ereated, as indicated a1; 12, 12; The

1 ;y1ead may be cemented in Ehe groove 18 formed accompanying drawing,in

IE is preferable, however, Ehat in amy form of cross section, Ehearrangement be such Ehat relatively large body por-Eions be disposed onopposiEe sides o1 Ehe embedded lead sErip so as Eo afford adequatesupporE for Ehe lead against latera1 Ehrusts. The rounded1ead-containing face arrangement shovvn in Fig. 4'may be advan- Eageous,especia]ly where draftsmen use a; long 7% sErip of commercial lumber fora sEraight edge, because Ehe finish on such lumber is sometirnescomparatively rough ancl Ehe rounded face of Ehe pencil will morereadily slide over such a rough edge. The rounded lead-containing face8i1 may also be desirable where Ehe pencil is Eo be usec1 in foflowingconeavely curved guiding edges.

As shown in Fig. 5, Ehe described pencil C011- struction may beadvantageously used where iE is desired Eo d1'aw a guide line acrossvarious 83" forms of mil1 werk in which Ehe face of Ehe work is noE a,smooth plane but contains recesses or valleys. As shown in Fig. 6, Ehedescribed. pencil .construction is advantageously used for drawing aguide line across warped lumber. In Fig. 7, Ehe 96 pencil isadvantageously used for drawing a guide 1ine around one cylindricalobject on Ehe surface 0f another. IE Will be seen EhaE because Ehe leadis disposed aE one sid.e 0f Ehe pencil, a vertical posiEion of Ehepencil against Ehe guiding member 9'53 will resulE in an' accuratelydravm guide line, even Ehough Ehe surface an which Ehe line is drawn Ehepencil moves up anc1 down relative Eo Ehe 53 guide element iE being onlyimportant EhaE Ehe vertical position qf Ehe pencil be maintained.

Changes in Ehe described structure may be made without deparEing fromEhe spiriE of Ehe invention, Ehe scope of which should be determined byreference to the following daims, the same being construed as broadly aspossible cousistent with the state of the art.

I daim:

l. A penci1 of the dass described, comprising a body and a strip ofwriting materia1 recessed into the body so that one face of the writingmaterial strip is substantially flush With the corresponding face of thebody, the writing material strip being of small cross sectionaldimensions compared with those of the pencil and disposed wholly at oneside of the pencil.

2. A pencil of the dass described, comprising a body and a strip ofW1iting material recessed into the body so that one face 0f the Writingmateria1 strip is substantially flush with the corresponding face of thebody, the body being re1a tive1y wide laut thin in cross section and thewriting material strip being recessed substantially cent1ally into oneof the wide faces of the body whereby the body portions 0n oppositesides of ehe st1ip afiord adequate Support for the strip When subjectedto lateral thrust.

3. A pencil of the dass described, comprising s a body am]. a strip ofwriting material reoessed into the body so thao one face of the writingmaterial strip is substantially flush with the corresponding face of thebody, ehe body beim; 01" relatively wide but thin, generally rectangularcross-section and having one of its wide Walls sub stantially flat, thewriting material strip being recessed centrally into said fiat face ofthe body whereby said flat face is adapted to engage a straight edge orthe 1ike to prevent turning of the penci1.

4. A pencil of the dass described, comprising a wood body having a,substantially fiat face and a strip 0f lead having a substantially fiatside, the lead strip beim; recessed into one side of the body so thatsa.id fiat side is substantially fiush With the flat face of the body,the lead strip being 01 small cross-sectional dimensions compared Withthose of the body and disposed whol1y at one side 05 the latter.

5. A pencil of the dass described, comprising a wood body of relativelywide but thin, generally reccangular cross-section, and a lead stripalso of rectangular c1oss section, said lead strip being recessed intoone of the wide faces of the body so as to position ehe unter face ofthe 1ead strip substantially flush with the face of the body.

6. A penci1 of the dass described, comprising a body having one faceon1y slightly convexly curved, and a lead strip recessed into saidcurved face of the pencil and having a face portion substantially fiushwith said curved face of the body.
